DESCRIPTION

The RX-3573 module is a ZigBee™ network solution that

based on Silicon LabsTM EM357 SoC which integrates !a

2.4Ghz, IEEE 802.15.4-compliant transceiver with an 32-

bit ARM Cortex M3 microprocessor. It contains integrated

Flash and RAM memory and peripherals of use to

designers of ZigBee-based applications.

The transceiver utilized an efficient architecture in which the

integrated receiver channel filtering allows for co-existence

with other communication standards in the 2.4Ghz

spectrum such as WiFi and Bluetooth.! An optional high

performance radio mode (boost mode) is software

selectable to boost dynamic range by a further 3dBm. The

highly integrated antenna, power regulator, and Xtal keep

the external component count low. The internal PCB

traced antenna and an external U.FL connector port is

user selectable1. This maximum the flexibility for the

designer to minimize the cost or maximize the system

performance.

The EM357 has 192kB of embedded Flash memory and

12kB of integrated RAM for data and program storage.

The EM375 software stack employs an effective wear-

leveling algorithm in order to optimize the lifetime of the

embedded Flash.

To support user-defined application, a number of

peripherals such as GPIO, UART, SPI, TWI(I2C), ADC, and

general purpose timers are integrated. Also, an integrated

voltage regulator, power-on-reset circuitry, sleep timer, and

low-power sleep modes are available. The deep sleep

mode draws less than 2uA, allowing products to achieve

long battery life. The equipped internal watch-dog timer

allows the system to be reactivated once the system go

into a dead-lock state. This mechanism makes the system

more reliable and available.
